[U-Boot] USB on iMX25
by Matthias Weißer 20 May '11

20 May '11

Hi I am currently porting u-boot to a new board based on Freescales iMX25 processor. I would like to add USB support. As I can see there is no support in current head for USB on iMX. Can someone give me some hints what I have to do to enable USB host support on iMX25. Matthias

[U-Boot] git merge summary
by Alexander Holler 11 Mar '11

11 Mar '11

Hello, may I ask if there is reason why merge commits don't have a summary? I find those summaries (enabled with git config [--global] merge.summary true) very hand to see what was changed with the merge commit. Regards, Alexander

[U-Boot] Atmel AT91 USB DFU and USB device port driver
by Krishna Pattabiraman 12 Feb '11

12 Feb '11

Hi All, I am currently developing a USB DFU feature for at91sam9263 board. I have to develop the driver for USB device port. I looked the uboot-usb git cdc branch it has a at91_udc.c driver it doesnt contain the udc_* api implementations. I found a earlier post where it was discussed. http://www.mail-archive.com/u-boot@lists.denx.de/msg08709.html Can any point give me a pointer to implement it or the implementations if exist. Bye, Krishna.

[U-Boot] [PATCH 0/5] New environment code
by Wolfgang Denk 17 Jan '11

17 Jan '11

The following patch series adds some utilities (qsort and hash table based database functions) and uses these to reimplement the code used for the internal handling of environment variables. Motivation: * Old environment code used a pessimizing implementation: - variable lookup used linear search => slow - changed/added variables were added at the end, i. e. most frequently used variables had the slowest access times => slow - each setenv() would calculate the CRC32 checksum over the whole environment block => slow * "redundant" envrionment was locked down to two copies * No easy way to implement features like "reset to factory defaults", or to select one out of several pre-defined (previously saved) sets of environment settings ("profiles") * No easy way to import or export environment settings ====================================================================== API Changes: - Variable names starting with '#' are no longer allowed I didn't find any such variable names being used; it is highly recommended to follow standard conventions and start variable names with an alphanumeric character - "printenv" will now print a backslash at the end of all but the last lines of a multi-line variable value. Multi-line variables have never been formally defined, allthough there is no reason not to use them. Now we define rules how to deal with them, allowing for import and export. - Function forceenv() and the related code in saveenv() was removed. At the moment this is causing build problems for the only user of this code (schmoogie - which has no entry in MAINTAINERS); may be fixed later by implementing the "env set -f" feature. Inconsistencies: - "printenv" will '\\'-escape the '\n' in multi-line variables, while "printenv var" will not do that. ====================================================================== Advantages: - "printenv" output much better readable (sorted) - faster! - extendable (additional variable properties can be added) - new, powerful features like "factory reset" or easy switching between several different environment settings ("profiles") Disadvantages: - Image size grows by typically 5...7 KiB (might shrink a bit again on systems with redundant environment with a following patch series) ====================================================================== Implemented: - env command with subcommands: - env print [arg ...] same as "printenv": print environment - env set [-f] name [arg ...] same as "setenv": set (and delete) environment variables ["-f" - force setting even for read-only variables - not implemented yet.] - end delete [-f] name not implemented yet ["-f" - force delete even for read-only variables] - env save same as "saveenv": save environment - env export [-t | -b | -c] addr [size] export internal representation (hash table) in formats usable for persistent storage or processing: -t: export as text format; if size is given, data will be padded with '\0' bytes; if not, one terminating '\0' will be added (which is included in the "filesize" setting so you can for exmple copy this to flash and keep the termination). -b: export as binary format (name=value pairs separated by '\0', list end marked by double "\0\0") -c: export as checksum protected environment format as used for example by "saveenv" command addr: memory address where environment gets stored size: size of output buffer With "-c" and size is NOT given, then the export command will format the data as currently used for the persistent storage, i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and prepend a valid CRC32 checksum and, in case of resundant environment, a "current" redundancy flag. If size is given, this value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32 checksum and redundancy flag will be inserted. With "-b" and "-t", always only the real data (including a terminating '\0' byte) will be written; here the optional size argument will be used to make sure not to overflow the user provided buffer; the command will abort if the size is not sufficient. Any remainign space will be '\0' padded. On successful return, the variable "filesize" will be set. Note that filesize includes the trailing/terminating '\0' byte(s). Usage szenario: create a text snapshot/backup of the current settings: => env export -t 100000 => era ${backup_addr} +${filesize} => cp.b 100000 ${backup_addr} ${filesize} Re-import this snapshot, deleting all other settings: => env import -d -t ${backup_addr} - env import [-d] [-t | -b | -c] addr [size] import external format (text or binary) into hash table, optionally deleting existing values: -d: delete existing environment before importing; otherwise overwrite / append to existion definitions -t: assume text format; either "size" must be given or the text data must be '\0' terminated -b: assume binary format ('\0' separated, "\0\0" terminated) -c: assume checksum protected environment format addr: memory address to read from size: length of input data; if missing, proper '\0' termination is mandatory - env default -f reset default environment: drop all environment settings and load default environment - env ask name [message] [size] same as "askenv": ask for environment variable - env edit name same as "editenv": edit environment variable - env run same as "run": run commands in an environment variable ====================================================================== TODO: - drop default env as implemented now; provide a text file based initialization instead (eventually using several text files to incrementally build it from common blocks) and a tool to convert it into a binary blob / object file. - It would be nice if we could add wildcard support for environment variables; this is needed for variable name auto-completion, but it would also be nice to be able to say "printenv ip*" or "printenv *addr*" - Some boards don't link any more due to the grown code size: AR405, CANBT, DU405, PMC440, canyonlands, sc3, sequoia, socrates. => cc: Matthias Fuchs <matthias.fuchs(a)esd-electronics.com>, Stefan Roese <sr(a)denx.de>, Heiko Schocher <hs(a)denx.de> - Dropping forceenv() causes build problems on schmoogie => cc: Sergey Kubushyn <ksi(a)koi8.net> - Build tested on PPC and ARM only; runtime tested with NOR and NAND flash only => needs testing!! Wolfgang Denk (5): Add basic errno support. Add qsort - add support for sorting data arrays Add hash table support as base for new environment code Remove support for CONFIG_HAS_UID and "forceenv" command New implementation for internal handling of environment variables.

[U-Boot] [PATCH] ppc4xx: Generic architecture for xilinx ppc405(v3)
by Ricardo Ribalda Delgado 24 Dec '10

24 Dec '10

As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda(a)uam.es> --- v2 Includes changes propossed by Stefan Roese -Remove unneeded init.S -PPC404 ->PPC405 v3 rebased to ppc4xx/master CREDITS | 1 + MAINTAINERS | 1 + Makefile | 16 ++ board/xilinx/ppc405-generic/.gitignore | 1 + board/xilinx/ppc405-generic/Makefile | 60 ++++++++ board/xilinx/ppc405-generic/config.mk | 25 ++++ board/xilinx/ppc405-generic/u-boot-ram.lds | 134 ++++++++++++++++++ board/xilinx/ppc405-generic/u-boot-rom.lds | 144 ++++++++++++++++++++ .../xilinx/ppc405-generic/xilinx_ppc405_generic.c | 59 ++++++++ board/xilinx/ppc405-generic/xparameters.h | 36 +++++ cpu/ppc4xx/start.S | 3 +- include/configs/xilinx-ppc405-generic.h | 58 ++++++++ include/configs/xilinx-ppc405.h | 126 +++++++++++++++++ 13 files changed, 663 insertions(+), 1 deletions(-) create mode 100644 board/xilinx/ppc405-generic/.gitignore create mode 100644 board/xilinx/ppc405-generic/Makefile create mode 100644 board/xilinx/ppc405-generic/config.mk create mode 100644 board/xilinx/ppc405-generic/u-boot-ram.lds create mode 100644 board/xilinx/ppc405-generic/u-boot-rom.lds create mode 100644 board/xilinx/ppc405-generic/xilinx_ppc405_generic.c create mode 100644 board/xilinx/ppc405-generic/xparameters.h create mode 100644 include/configs/xilinx-ppc405-generic.h create mode 100644 include/configs/xilinx-ppc405.h diff --git a/CREDITS b/CREDITS index 3767322..9ddf0d2 100644 --- a/CREDITS +++ b/CREDITS @@ -407,6 +407,7 @@ N: Ricardo Ribalda Delgado E: ricardo.ribalda(a)uam.es D: PPC440x5 (Virtex5), ML507 Board, eeprom_simul, adt7460, v5fx30teval D: Virtex ppc440 generic architecture +D: Virtex ppc405 generic architecture W: http://www.ii.uam.es/~rribalda N: Stefan Roese diff --git a/MAINTAINERS b/MAINTAINERS index 60cb6a6..a5d1038 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -320,6 +320,7 @@ Ricardo Ribalda <ricardo.ribalda(a)uam.es> ml507 PPC440x5 v5fx30teval PPC440x5 xilinx-pp440-generic PPC440x5 + xilinx-pp405-generic PPC405 Stefan Roese <sr(a)denx.de> diff --git a/Makefile b/Makefile index fceb8a2..66922eb 100644 --- a/Makefile +++ b/Makefile @@ -1518,6 +1518,22 @@ sycamore_config: unconfig WUH405_config: unconfig @$(MKCONFIG) $(@:_config=) ppc ppc4xx wuh405 esd +xilinx-ppc405-generic_flash_config: unconfig + @mkdir -p $(obj)include $(obj)board/xilinx/ppc405-generic + @echo "LDSCRIPT:=$(SRCTREE)/board/xilinx/ppc405-generic/u-boot-rom.lds"\ + > $(obj)board/xilinx/ppc405-generic/config.tmp + @echo "TEXT_BASE := 0xFE360000" \ + >> $(obj)board/xilinx/ppc405-generic/config.tmp + @$(MKCONFIG) xilinx-ppc405-generic ppc ppc4xx ppc405-generic xilinx + +xilinx-ppc405-generic_config: unconfig + @mkdir -p $(obj)include $(obj)board/xilinx/ppc405-generic + @echo "LDSCRIPT:=$(SRCTREE)/board/xilinx/ppc405-generic/u-boot-ram.lds"\ + > $(obj)board/xilinx/ppc405-generic/config.tmp + @echo "TEXT_BASE := 0x04000000" \ + >> $(obj)board/xilinx/ppc405-generic/config.tmp + @$(MKCONFIG) xilinx-ppc405-generic ppc ppc4xx ppc405-generic xilinx + xilinx-ppc440-generic_flash_config: unconfig @mkdir -p $(obj)include $(obj)board/xilinx/ppc440-generic @echo "LDSCRIPT:=$(SRCTREE)/board/xilinx/ppc440-generic/u-boot-rom.lds"\ diff --git a/board/xilinx/ppc405-generic/.gitignore b/board/xilinx/ppc405-generic/.gitignore new file mode 100644 index 0000000..b644f59 --- /dev/null +++ b/board/xilinx/ppc405-generic/.gitignore @@ -0,0 +1 @@ +config.tmp diff --git a/board/xilinx/ppc405-generic/Makefile b/board/xilinx/ppc405-generic/Makefile new file mode 100644 index 0000000..b56bb49 --- /dev/null +++ b/board/xilinx/ppc405-generic/Makefile @@ -0,0 +1,60 @@ +# +# (C) Copyright 2000-2006 +# Wolfgang Denk, DENX Software Engineering, wd(a)denx.de. +# +# (C) Copyright 2008 +# Ricardo Ribalda-Universidad Autonoma de Madrid-ricardo.ribalda(a)uam.es +# Work supported by Qtechnology http://www.qtec.com +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

by Wolfgang Denk 22 Dec '10

22 Dec '10

Hi everybody... v2009.08-rc3 has just been released. Please help testing, and submit fixes to the remaining problems. Things still missing should be submitted ASAP. * Many boards now throw the (expected) #warning Ethernet driver is deprecated. Please update to use CONFIG_NET_MULTI messages. * ARM, MIPS and PowerPC: mostly compile clean; there are a few issues (mostly harmless) - responsibles have been notified Comments and fixes welcome. Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de 'What shall we do?' said Twoflower.
